In the early 60's I had a nice 1956 Corvette with the racing package that included two four barrel carbs, fast steering and a 3.55 final drive.
There is a sports car racing track nearby and if I joined a local sports car club I could race there in the 'cruising' race that allowed passing on the straight which was long.
I was up against those tiny MG's and maybe a Jag 120.
I paid the $10 entry fee and I was in the paddock waiting my turn as others finished their turn.
Into the paddock came a Porsche with corkscrew gouges all along one side from brushing with another cars wire wheel spinner!
I went up and asked for my $10 back!
